Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

Advanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a

Physical Adsorption‐Driven Assembly of Au‐Locked Nucleic Acid (LNA) Probes on MoS2 Nanosheets for SERS‐Based Detection of microRNAs (miRNAs)

Advanced Materials Interfaces, EarlyView.
The Au‐LNA Raman probe, composed of gold nanoparticles (AuNPs), thiol functional group, and Cy3 modified LNAs, synthesized after hybridization of LNA and miR‐210‐3p target, is integrated into the MoS2@Au composite. The integration of the nanocomposite is formed by physical adsorption of Au‐LNA nanohybrid with MoS2. Characterization confirms morphology,
